Application January 19, 1950, Serial No. 139,347

My invention relates to cap releasers and more particularly to those adapted for use on any bottle or can capable of being sealed or capped by means of a crown cap.

The object of my invention is to provide an article of this type capable of accomplishing its intended purpose with such facility and efiiciency' that together with its novel features which permit its economical manufacture, it willbecome generally used.

A further object is to provide an article of this type which may be easily placed on and is securely held in'position on a bottle or can during the application thereto of a sealing cap.

A further object is to provide an article of this type which in no way interferes with the complete seal of the bottle or can when any sealing cap of well known or approved construction is used.

A further object is to provide an article of this type which is so constructed that it will accomplish its intended purpose when lifted outwardly and longitudinally away from the bottle or can wall, or when pushed laterally.

A further object is to provide an article of such construction that it can be actuated and removed from contact with the cap and bottle or can leaving the cap susceptible to easy manual removal when desired.

Another object is to provide an article of this type which does not impede the packing or shipping of containers provided with same and which also provides additional space for advertising media if so desired.

vA further object is to provide a cap releaser which will enable the above and other objects to be effectively attained.

Broadly, my invention comprises a cap releaser including a top section having gripping means formed integral therewith and adapted to hold the releaser in place on the bead of a bottle or can, and a handle portion depending therefrom and formed integral therewith, said handle being provided with a weakened section to assist in the efficient operation of the device as will be set forth below.

Practical embodiments of my invention are shown in the accompanying drawings in which: Fig. 1 represents a detail side elevation of one embodiment of my invention applied to a bottle; Fig. 2 represents a detail front view of the form shown in Fig. 1;

- As the principles of my cap releaser are similar in all the forms shown, it is denoted in all figures by I, the bottle by 2, the can by 3 and the cap by 4. The releaser l comprises'a top secto operate the releaser I.

half the circumference of the top bead I1 i. e., to the form shown in Figs. and 11; its fingers l0 bent inwardly, and then it is lowered vertically over the top either manually or otherwise before same is capped in any well known or approved manner. Releaser I is pushed down over the top of bottle 2 or can 3 until fingers l0 engage the upper surface of bead l'l slightly below the extreme top plane thereof. In this position projections l4 and inwardly bent lower edges 8, 9 of wings 6, 1 will engage the lower surface of said bead ll, thereby cooperating with fingers ID to grip the bead l1 and hold the releaser l in proper position for subsequent operation as well as preventing its accidental displacement during the usual capping. It will be noted that this exact positioning of releaser l by the cooperation of its several components with the bottle bead only, together with the gauge of metal or other suitable material of which the releaser may be formed permits a perfect seal to be obtained by the application of the usual sealing cap 4 provided with a cork liner l8 as shown in Figs. 4 and 5.

It will be understood that any combination of fingers I0, projections l4, and/or bent lower edges 8, 9 of wings 6 and 1 can be used to support releaser l on and grip it to bead l1 so long as an opposed combination thereof is employed to squeeze the bead. The resiliency-of the metal or other suitable material permits the releaser to be used on a wide variety of bottles, cans, and the like, although it is sometimes necessary to furnish it with a deeper arc than the form shown in Fig. 8 if the bottle 2 or can 3 is of squat construction in order that the handle may lie close to the side thereof.

When the bottle 2 or can 3 has been sealed by crimping the cap 4 thereon and it is desired to open same, an upward lift on handle H moves wings 6 and I downward due to the fulcrum effect of the rear central projection l9 against bead H. In the form shown in Figs. 11 and 13 a back projection resulting from a punch is denoted by 2D. This downward movement is facilitated by the tendency of the handle H to bend or buckle at weakened point l6 since this accentuates the force applied through the doubled edges of handle ll. After slight downward movement of the wings 6 and I handle ll will contact the lower edge of cap 4 and, if the lift is continued, wings 6, l and some fingers ID are removed from between the vertical walls of cap 4 and the outer periphery of bead l1 thereby freeing the cap from the bottle or can to a certain extent but Without breaking the seal. Further lifting forces handle ll against the lower edge of cap 4 which will be raised thereby if the lift is continued.

It is possible before the cap 4 is lifted off to lower handle I I, remove releaser l and when de sired open the bottle 2 or can 3 merely by pushing up the cap 4 with ones fingers to break the seal; a very advantageous feature when a beverage, for example, is not intended for immediate consumption.

A crimped sealing cap is so slightly deformed when removed through the use of my invention that it can be reapplied to the bottle by hand and similarly removed as often as desirable.

Since it is evident that various changes may be made in the construction, form and arrangement of the several elements of my invention, 1 do not intend to be limited to the specific embodiments herein shown and described except as set forth in the appended claims.
